Altuve has been one of the hottest hitters on the team during this stretch. The All-Star second baseman has notched a hit in 21 of his last 23 games and is batting .339 (37-for-109) over the last 28 days.

After struggling to start his career, Springer was named the American League Rookie of the Month after hitting .294 with 10 home runs in May.

Singleton, who was called up more recently, has also dealt with his share of Major League adjustments. He's hitting only .200 (5-for-25) with a pair of home runs through his first six games.

But on Sunday against the Twins, he and teammate Chris Carter hit a pair of grand slams, becoming the first Astros teammates since 1969 to each hit grand slams in the same game.

"Springer and Singleton, they're really good guys," Altuve said. "They have not too much time here, but they're showing people what they can do … They're going to be really good."

Although they've been rolling of late, pitcher Brad Peacock, who will get the ball against the D-backs in the second of two games this week at Chase Field, said the team's hot play doesn't affect him on the mound.

"The starters try to follow up on one another and try to compete with each other," Peacock said. "But I'm just going to try to go out there and locate pitches and do my job."
